STEM-=WINDER MECHANlSM FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 314,288, dated March24, 1835.

Application filed August 15, 1881.

T0 aZZ whom it may concern:

Be it known that I, ALLEN S. GALENTINE,

a citizen of the United States, residing at Valparaiso, in the county ofPorter and State of 5 Indiana, have invented certain new and use fulImprovements in Stein-Setting atches, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention has relation to improve ments in stenrwinding watches;and it consists in the construction and novel arrangement of the same,all as will be hereinafter more fully explained.

The annexed drawings, to which reference is made, fully illustrate myinvention, in which Figure 1 represents a rear view of the works of awatch with the outer plate removed. Fig.2 is a front view of the same 20with the dial removed; and Fig. 3 is a side view, part sectional, ot'the pin and stem detached from the watch.

Referring by letter to the accompanying drawings, A designates thehousing, in which 25 the works of the watch are placed, and the stem ofthe watch-case is provided with a perforation which extends from theouter end thereof to the inner face of the annular rim of the casing andis in a line with the rect- 0 angular opening formedin the pinionb,which operates the setting andwinding of the watch. 0 represents theoperating stem or key, whichis provided with a central verticalperforation, c, and a cylindrical body, I), the in- 5 ner end of whichis rectangular in cross-see tion and shouldered at c at the lower end ofthe cylindrical portion.

Within the perforation or passage of the stem B is an operating-pin, D,which is pro- 4.0 vided at one end with a plain point, d, and at theopposite end with the push button or head d, that fits within the recessd in the upper end of the stem 0, and this push-pin is do i signed to belonger than the length of the stem 5 aforesaid.

E indicates a springarm, the inner end, 6, of which is rigidly securedto the pillar-plate e, and the outer free end, 0 is provided with (Nomolcl.)

a lip, c", projecting at right angles to the arm, and extending througha slot, 6, (made in said plate) and rests upon the point ot' the pivotedplate f, which has attached thereto the several gear-wheels and pinion,which are thrown in and out of engagement with running mechanism of thewatch, and this plate f is pivoted to the pillar-plate e, as shown atfThe spring-arm aforesaid is arranged below the pinion, and the push-pinD by its point rests gently upon the middle portion, f.

It will be observed by reference to the annexed drawings that in orderto set the hands of the watch the operator presses upon the push-pin D,which, by its lower end, forces the spring-arm downwardly upon the pointf, and thus turning the plate f upon its pivotf thereby causing thepinion b to mesh with the pinion g 011 the arbor, and by turning thestem when the pressure is on said puslr pin the hands of the watch canbe set forward or backward, as desired. At the same time when the partsare connected to set the hands the winding mechanism is disconnected.Atterthe handsare set and the pushpin is released from pressure, andassumes its normal position, the gearing above mentioned separates bymeans of the spring, forcing the plate to turn on its pivot, and when inthis position the watch can be wound up by turning the stem 0, thusoperating the pinion g, and by means of which the train of gearing isoperated in winding up the watch.

It will be seen that the winding of the watch and setting the same areentirely independent of one another, and both of the move ments cannotbe accomplished exactly at the same time, and the button or head of thepush-pin lies within the recess of the stem, and therefore cannot beaccidentally struck or come in contact with obstructions.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

In a stem winding and setting watch, the combination, with the pivotedplate f, provided with the point f, stem (J, casing A, plate 6',provided with the opening 0, of the El i-.288

spring-arm E, pivoted at e, and provided at In testimony whereofI affixmy signature its end, 0 with the lip 0", passing through the in presenceof two witnesses.

opening 0, and engaging the point f, the pushpin D, adapted to engage byits point (1 said arm, whereby the train of gearing on the platef isthrown in and out of engagement, substantially as described, and for thepurposes set forth.
